Medical Terminology-Body Organization Flashcards
Cardiology
Study of the heart.
Dermatology
Study of the skin.
Endocrinology
Study of the endocrine glands.
Gastroenterology
Study of the stomach and intestines.
Gynecology
Study of women and women’s diseases.
Hematology
Study of blood.
Neurology
Study of the nerves and the brain and the spinal cord.
Oncology
Study of tumors (cancerous or malignant diseases).
Ophthalomology
Study of the eye.
Pathology
Study of disease.
Psychology
Study of the mind and mental disorders.
Rheumatology
Study of joint diseases.
Root word
Give the meaning to the term. (i.e. HEMAT/O/LOGY: HEMAT=root meaning blood).
Combining vowel
Connects root to suffixes and roots to other roots (i.e. HEMAT/O/LOGY: /O/ = combining vowel).
Suffix
Is the word ending (i.e. HEMAT/O/LOGY: LOGY= suffix meaning study of).
Prefix
Is a small part added to the beginning of a term (i.e. bi=two, an= without, ab=away from, ad=near)
Combining form
Is the combination of the root and the combining vowel.
Anatomy
Study of body structure.
Physiology
Study of body function.
Body level organization
Chemical-Cell-Tissue-Organ-System-Organism (smallest to largest).
Skeletal system
Provides the basic framework or support needed by the body.
Muscular system
Provides body movements.
Circulatory system
Provides means of transportation for the body.
Digestive system
Involves the intake and breakdown of food.
Respiratory system
Involves the intake of oxygen and the release of carbon dioxide.
Integumentary system
Consists of the skin and its appendages which include the hair, the nails, and sweat and oil glands.
Urinary system
Involved with the elimination of waste and water, and its main components are the kidneys, the ureters, the bladder and the urethra.
Nervous system
Concerns itself with the receipt of stimuli and control of responses.
Endocrine system
Produces hormones which regulate growth, metabolism and reproduction.
Reproduction system
Produces offspring.
Frontal plane
Is the plane that is cuts down the middle of the body creating front (ventral or anterior) and back (dorsal or posterior) parts.
Sagittal plane
Is the plane that cuts the body in two from front to back, separating it into right and left portions.
Transverse plane
Is the plane that cuts the body and divides it into an upper (superior) part and a lower (inferior) part.
Catabolism
Is destructive (breakdown) metabolism. Complex compounds are changed into simpler ones with the release of energy. (i.e. burning glucose for energy).
Anabolism
Is constructive metabolism (building up). Simple compounds are changed into more complex ones with the use of energy (i.e. building new proteins such as muscle).
Homeostasis
Defined as the state of balance with in the body; in order to maintain homeostasis, the body must use methods of transport to move substances across cell membranes or through tissue membranes.
Negative feedback
Is a feedback loop where a stimulus (deviation from a set point) is resisted through a physiological process that returns the body to homeostasis. Negative Feedback loop has four parts; Stimulus, Sensor, Control and Effector. (i.e. Body temp regulation).
Dorsal body cavity
Contain two cavities; the cranial (brain) and the Spinal canal (encloses the spinal cord).
Ventral body cavity
The cavity that includes the thoracic cavity (stomach, intestines, kidneys, liver, gallbladder, pancreas and spleen) and the abdominal cavity (urinary bladder, reproductive organs and rectum). These two cavities are separated by the diaphragm.
Metabolism
The physical and chemical processes by which the body is maintained; it is the sum of all energy-producing reactions and/or reactions requiring energy.
Anatomical position
A set of position of the body for using directional terms (i.e. body stands erect, arms at the sides and the palms facing forward).
Erect position
The standing position.
Supine position
Lying on the back or on a dorsal surface.
Prone position
Lying face downward or on the ventral surface.
Superior direction
Meaning above or higher than.
Inferior direction
Meaning below or lower than.
Anterior or ventral direction
Meaning in front of; on the belly side.
Posterior or dorsal position
Meaning in back of; on the backside.
Medial position
Toward the midline of the body.
Lateral position
Toward the side or away from the midline of the body or part.
Proximal position
Nearest the point of attachment or origin of a part.
Distal position
Further away from the point of attachment or origin of a part.
Peripheral (adjective)
Toward the outer part or surface of the body or part.
Superficial
Near the surface.
Deep
Away from or below the surface.
Internal
Within the body, within or on the inside.
External
Exterior, outside the body or part.
Cranial cavity
Part of the Dorsal cavity, the cavity that contains the brain.
Spinal canal
Part of the Dorsal Cavity, the cavity that encloses the spinal cord.
Thoracic cavity
Part of the Ventral Cavity. The cavity that contains the heart and lungs.
